摘　　要：介绍了一种环氧树脂铸造用下芯框的快速制模技术。该下芯框制模工艺是采用下芯框框架作为四周骨架,浇注环氧树脂混合料,加热固化成形的一种制模技术。用该工艺制得的下芯框具有稳定的力学性能、尺寸精度、表面硬度和表面粗糙度,以及良好的耐磨性和使用寿命,具有很高的性价比。与传统在CNC机床上经过坯料加工而成的金属下芯框相比,在降低成本的同时,大幅缩短了制模周期,加快了铸造新产品研发和备用下芯框制模的过程进度。A rapid molding technology of the core mask made of epoxy resin was introduced.The manufacturing process of the core mask adopts the core mask frame as the surrounding skeleton,pouring the epoxy resin mixture,and heating and curing molding.The core mask made by this process has stable mechanical properties,dimensional accuracy,surface hardness and surface roughness,as well as good wear resistance and service life,and has a high cost performance ratio.Compared with the metal core mask processed by blank on the traditional CNC machine tool,the production cycle is greatly shortened while the cost is reduced,and the process progress of new casting product development and spare core mask production is accelerated.
